Description
Предлагаемое приспособление предназначено дл регулировани скорости секторного затвора в фотографических камерах.The proposed device is intended to control the sector shutter speed in photographic cameras.
Изображенное на схематическом чертеже приспособление состоит из маховичка 1, на ось 2 которого насажено зубчатое колесо, служащее дл поворачивани маховичка на определенный угол при помощи зубчатого сектора 3, качающегос на оси 7. Палец последнего находитс под действием кулачкового выступа на заводном барабане или кольце 8. Другой кулачковый выступ последнего приводит в действие сектор 10 открывающий или закрывающий отверстие в диафрагме 13.The device depicted in the schematic drawing consists of the handwheel 1, on the axis 2 of which a gear wheel is mounted, which serves to turn the handwheel at a certain angle with the help of the gear sector 3 swinging on the axis 7. The finger of the latter is under the action of a cam lug on the winding drum or ring 8. The other cam lug actuates the sector 10 opening or closing the hole in the diaphragm 13.
Дл регулировани величины торможени маховичка 1 служит кулачковый диск 5To control the deceleration of handwheel 1, use a cam disc 5
Предмет изобретени .The subject matter of the invention.
Приспособление дл регул и ров а ни sss скорости секторного затвора, отличающеес применением маховичка 1, на ось Z; которого насажено зубчатое колесо, служащее дл поворачивани маховичка на определенный угол при посредстве ка-чающегос на оси 7 зубчатого сектора 3,, палец которого находитс под действием кулачкового выступа на заводном барабане или кольце 8.A device for regulating the sss of the sector gate speed, characterized by the use of handwheel 1, on the Z axis; which is fitted with a gear that serves to rotate the handwheel at a certain angle by means of the toothed sector 3, the finger of which is under the action of a cam lug on the winding drum or ring 8.
2. При приспособлении, указанное в п. 1 применение кулачкового диска 5 дл регулировани величины торможениж маховичка 1.,2. When adjusting the use of the cam disc 5 for adjusting the braking magnitude of the handwheel 1.,
